CVE-2026-32766: Tar Pax Extension Silent Error Skip
Silently skipping malformed PAX extensions by using `filter_map(|f| f.ok())` can conceal parsing errors and lead to parser differentials. This behavior can be exploited if a subsequent component interprets the skipped malformed extension differently. Propagate the error using `?` or handle it explicitly instead of suppressing it.
